Patent GB-2114771-A (GB)
Title: Optical cable manufacture
Inventor: KACZMARSKI EDWARD ZBIGNIEW
IPC: B29C48/06
Filed: 1983-02-15
Abstract: An optical cable is manufactured by causing a reinforcing member 10 to travel through the extrusion orifice of the extruder (1) and by extruding about the advancing wire a circumferential plastics wall 14 having in its internal surface circumferentially spaced, longitudinally extending grooves. Those parts of the internal surface of the wall 14 between the grooves are bonded to the external surface of the wire 10 so that the grooves are closed by the reinforcing member to form elongate compartments and optical fibres 17 are fed into the grooves as the wall is formed; each optical fibre having such a diameter having regard to the size of its associated groove that it is loosely housed in the elongate compartment. Preferably, the advancing member 10 has an inner metallic core and an outer layer of plastics material. The die 2 forming the grooves in the internal surface of the wall 14 and through which the optical fibres 17 are fed may be oscillated so that the grooves have a continuously reversing lay. <IMAGE>

Title: A vehicle drive apparatus
Inventor: HASEGAWA SHIGEKAZU
IPC: B60W30/18
Filed: 1983-06-01
Abstract: The drive apparatus of a tractor comprises an engine (E), a main clutch (2) and a power shift change-speed transmission (1). The main clutch (2) is mounted downstream of the power shift transmission (1). Owing to the lower inertia involved in changing the speed ratio of the transmission (1) with the clutch (2) so disposed, a lower change-speed shift force is necessary. This allows the power shift means of the transmission (1) to be made smaller. The drive apparatus further comprises an auxiliary change- speed mechanism 3 incorporating a reversing means, and a super- reduction mechanism 4. The clutch 2 is automatically operated, and two or four wheel drive is possible. A power take-off shaft 12 is driven through a change speed mechanism 10 and a clutch 11. <IMAGE>

Title: Darts
Inventor: AHEARNE RODERICK MICHAEL
IPC: F42B6/00
Filed: 1984-01-21
Abstract: A dart has a barrel (12) with a bore (13) into which a plurality of weights (26) having different specific gravities can be inserted to adjust the weight and balance of the dart. The barrel may be formed in two parts which can be connected together and which can themselves be of different weights to allow further variation. The front end (16) of the bore (13) of the barrel and the rear end (23) of the point (22) have cooperating tapers normally held engaged to prevent relative pivotal movement. An elastic plug (25) in the bore allows limited inward movement of the point into the barrel on impact of the dart thus allowing limited relative pivoting at the moment of impact. <IMAGE>

Title: Programmable AC power line converter
Inventor: PACIOREK RAYMOND MICHAEL
IPC: H02M5/257
Filed: 1984-07-31
Abstract: A device and method for averaging AC power to permit operation of an appliance on a power line having a voltage substantially higher than the design operating voltage of the appliance. A counter (IC1) counts a predetermined number of cycles of line power and resets. A control signal is emitted during only one of the cycles during each counting period. Switching means (Q1, IC2) are operative in response to the control signal to permit line power to be applied to the load only during the one cycle. The switching means employs light emitting (D2) and detecting devices for isolating the control signal from the line power applied to the appliance. <IMAGE>

Title: Manipulator
Inventor: VICKERS MARK GORDON
IPC: B25J17/02
Filed: 1985-04-12
Abstract: A manipulator comprises three arms 1 which can pivot at different points on a supporting structure 6 and which can be driven longitudinally to adjust their effective lengths. The longitudinal axes of the three arms intersect at a common point but their lower ends are offset from this point and are pivoted about respective axes which also intersect at the aforementioned common point. They are pivotted to an end effector mounting flange 8 which optionally comprises a fourth arm 11 which slides and pivots on the supporting structure.

Title: A manual tractor
Inventor: KLUFIO EBENEZER SOWA
IPC: A01B1/02
Filed: 1985-09-17
Abstract: Man-propelled wheeled soil working equipment comprises a driving-arm 10 and an uniaxially mounted lever system. This includes a trailing lever load-arm 9 and a central lever unit made up of a primary-arm 1 and fork-arm 2. Attachments such as the scraper 11, are bolted to the load-arm. The driving-arm 10 is so secured to the primary-arm 1 that pushing on its handles causes the scraper 11 to be pressed into, and drawn through the soil, thus working the land. The equipment converts to carrier (fig 6) when the driving-arm is swung to the side opposite the load-arm and a box is fastened on top of the load-arm. Further, removing the box and replacing the lower attachment by a scooping implement converts the machine into a shovel. <IMAGE>
